' settingtoolQ EYELET Application filed October 5,1923, Serial No.666,862, and'in Germany September 13,1923. Renewed L A :n rn 9, 1927., II r This inventib'nrelates to eyelets and isidisclosed herein withparticular reference to eyelets especially adapted to be'used for invisible eyeleting in the manufacture of boots and shoes. 7 g V 1 p Inorder to insure that the .outer layer'of the stock will be properlyforced past the clenching shoulder of the setting tool in the. insertionof invisibleeyelets, it is an object of the present invention to providean improved eyelet having the end of its barrel'f-ormed to provideeffective means to push the stockin which the eyelet is to be insertedalong'the pilot ofthe setting tool and ultimately to force the outerlayer of the stock past the clenching shoulder of the tool. Furtherobjects of the invention are to provide an eyelet for invisible,eyeleting which will be satisfactory in the best grades of shoes andwhichcan, at the same time, be produced in quantity at a cost which willpermit its .usein-shoes of anytype or grade in which. it is desired toinsert invisible eyelets.

. With these objects in view, the herein dis closed eyelet is providedwith a blunted, polygonal or scalloped end providinga plurali ty ofoutwardly projecting, stock-pushing portions arranged to engage theworkat points rem-ovecl fro1n the lacing hole, alternating with apluralityof portions arranged to engage the edge of the lacing hole,this formation being such as to insure that the upper leather isproperly forced past the clenching shoulder of the setting tool and alsofacili tating the ready passage of the end ofthe eyelet barrel throughthelacing holeand the clenching thereof between adjacent layers of Inorder to cause the prongs formed when the eyelet bursts to curlprogressively outwardly and downwardly toward the flange of the eyeletas they pass the clenching shoulder of the setting tool, the portion ofthe barrel of theillustrated eyelet at and adjacent to its entering endand extending a substantial distance towards the flange of the eyelet isof a non-tapered formation so that the eyeletbarrel has a long bean ingupon and closely embraces the pilot of the While the invention isdisclosed herein in connection with an. eyelet particularly intended forinvisible eyeleting in the manufac ture of shoes, it should beunderstood that in various of its aspects it is not so limited,

With the above and other objects in view,

the invention will now be described in connecti'on with the accompanyingdrawings and view, respectively, oftheeyelet prior tothe performance ofthe final upsetting and blunting of the end of its barrel;.

Fig. 11 is a cross section on the line 1111 of Fig. 10, with the eyeletomitted; and

Figs. 12 and 13. illustrate the upsetting and blunting of the enteringend of the eyelet V v i 7 tween the successive scallops. At its enteringend the eyelet barrel is upset and blunted,

as show'nat 108, so as to provide a flat'or 7,100

' layers of a shoe upper along the plane work-engaging end surface of aform effective as a pushing member to push the pilot 110 of an invisibleeyeleting tool 112 (Fig. 6) and ultimately to force the outer layer 114(that is, the upper leather) past the clenching shoulder of the settingtool; The" scalloped formation of the entering end of the eyelet barrelis of material assistance in forcing the outer layer 11a of the stockpast the clenching shoulder 116 of the setting tool 112 in that itprovides the entering end of the barrel with effective pushing portions118 (Fig. 6) at and adjacent to the apexes of the scallops which engagethe material at points or over an area removed from the lacing holethereby, during the relative movement of the eyelet and the setting tool112, forcing the outer layer of the stock past the clenchingshoulder'116 of the setting tool. On the other hand, this polygonal orscalloped formation also permits portions of the end of the eyeletbarrel to engage the edge of the lacing hole and to embrace closely thepilot 110 of the setting tool 112 so as to facilitate the passage of theend of the barrel through the facing or lining 119 and the eyelet stay120 of the shoe upper, the abutment 122 preventing the up per leather 11from being forced too far past the clenching shoulder 116.

As illustrated, this scalloped formation extends more than halfway fromthe entering endtoward the flange of the eyelet. Morethe flange.

over, the portion of the barrel of the illus trated eyelet at andadjacent to its entering end, and extending approximately halfway to theflange of the eyelet, is of a substantially non-tapered formation, theremainder of the barrel flaring at a considerable angle toward Thus theinternal diameter of the eyelet barrel, measured on any longitudinalplane of cross-section, is substantially uniform at all points in saidplane between its extreme end and the beginning of the flaralso causesthe hole through the clenched eyelet to be larger than the hole throughthe entering end of'the barrel of the unclenched eyelet, since asubstantial part of the flaring portion is split and turned back whenthe eyelet is clenched. Accordingly there is no danger that the holethrough the clenched eyelet will be too small to permit the passage ofthe tip of a shoe lacing.

v This novel eyelet may conveniently be 108, Fig. 13.

formed from a blank having the flange and barrel of the ordinary eyelet,by scalloping and scoring the barrel, as indicated in Figs. 4 and 5, bytools illustrated in Figs. 7 to 11 and by subsequently upsetting andblunting the entering end of the barrel, as shown in Figs. 12 and 13, aswill be more fully described.

In Figs. '4', 8, 10 and 11 is shown a hollow die member 124 formed witha series of ribs 126 separated by grooves 128, the ribs 126 tapering offat the entering end of the die, as shown at 130 (Fig. 7), thus formingan enlarged entrance 131. Conveniently at itsentering end the die isprovided with a recess 132 adaptedto receive the flange of the eyeletblank to be operated upon. A punch 134, illustrated in Figs. 9, 1Oand'll, is used in cooperation with die 12 lto scallop and score theeyelets. This punch is itself scalloped, as clearly shown in Figs. 9 and11, the successive scallops meeting and forming cutting edges 136. Theentering end of punch 134 is tapered to facilitate its introduction intothe barrel of an eyelet which has previously been introduced into die124. as shown in Fig. 10. shoulder 137 which co-operates with recess132'of'die 124 properly to limit the movement of punch 13a relatively toan eyelet operated upon. The punch 13% enters the portion of the eyeletbarrel adjacent to the eyelet flange freely and without obstruction but,as it passes toward the smaller entering end of the eyelet barrel, edges136 of the punch score the interior of the barrel, finally cutting allthe way through the barrel at the entering end thereof. At the same timethe barrel is scalloped, being forced into the space (indicated at 138,Fig. 11) between the punch 13 1 and die 12 1. Punch 134i is passedthrough die 124i approximately to the position indicated in dotted linesat 1&0 in Fig. 10, after which it is withdrawn leaving thejeyelet in thecon dition shown in Figs. 1 and 5, with a thin,

sharp edge 1 1-2 at its entering end. After this the eyelet is placedupon a spindle 14A (Fig. 12) having a shoulder 1&6 arranged to supportthe flange 100 of the eyelet adjacent to the lacing hole and having atapered portion 1418 terminating in a cylindrical portion 150 arrangedsubstantially to fill the entering end of the eyelet barrel. Cooperatingwith spindle is a die 152 having a hole therethrough of a size to be agood working fit on the cylindrical portion 150 of spindle M l. lViththe eyelet supported upon spindle 1 1%, as indicated in Fig. 12, die 152and spindle 144 are, given relative movement so as to force die 152against the end of the eyelet barrel supported upon the cylindricalportion 150. of the spindle, upsetting and blunting the end of theeyelet barrel, as shown at Die member 152 is then withdrawn and theeyelet removed from spindle Punch 18a is provided also with a 144, afterwhich the substantially completed eyelet may be subjectedto any desiredfinishing operation. This method of manufacturing eyelets is'not claimedherein, since it 30, 1925, as a division of this application. e

By reducing-the depth'of grooves 128 in die 124 and by correspondinglyreducing the size of punch 134, the depth of the scalloping of theeyeletmay be reduced. Indeed this may be carried to such anzextent thatthe entering end of the eyelet-barrel will take the form of a polygoneach of whose sides is a straight line instead of the curved line shownin Fig. 5.- Eyelets so formed,v or scalloped eyelets formed as shown inFigs.'4 and 5 Without the upset or blunted end, are more effective thanthe sharp-ended circular eyelets of the prior art in pushing the layersof the shoe upper along the pilot of an invisible eyeleting tooland inforcing the upper leather past the clenching shoulder of the tool, sinceportions of the end of the'eyelet barrel engage the stock at pointsspaced from the lacing hole,

though such eyelets are less effective in this respect than the eyeletof Figs. 1, 2' and 8. However, since such eyeletsvare cheaper tomanufacture (the upsetting and blunting being omitted), and since theyoperate satisfactorily with many kinds of stock, they are of realutility in the art and are considered to be within the scope of thepresent invention.
